but!

I've read through some posts in here like this one
http://forum.x-cart.com/viewtopic.php?t=8138 and I'm just missing something. I got an SSL from Geotrust. They sent me an email saying to paste this:
Code:
Install QuickSSL Premium
To install the QuickSSL Premium Smart Icon seal, simply add the following lines to each web page on which you want the QuickSSL Premium seal to appear:
Code:
<SCRIPT LANGUAGE="JavaScript" TYPE="text/javascript" SRC="//smarticon.geotrust.com/si.js"></SCRIPT>
I'm about a week old to PHP,infact bought the software on the 22nd of this month, and aren't sure what to do. I pasted it into the cart page but got an error. I've read just about everything but like I said"I'm missing something" I know when I go to the website I'm building for my wife and login and go thru the checkout process like I'm buying something the cart.php is secure
Code:

I'm just not sure where to put the script that retreives the Geotrust logo. I'd appreciate if someone could point me in the right direction as to where to insert the Geotrust script or what template/s to edit and how. The site is "
www.riverviewflorist.net" if anyone wants to go look. I also get a security alert popup when I go from
http://riverviewflorist.net/xcart/cart.php?mode=checkout
to
https://riverviewflorist.net/xcart/cart.php?paymentid=1&mode=checkout&xid=6f933dd32a8 c8c85a9ae591498120071. But only after I log out and back in. Infact if you click the link above you'll see it. Like I said, I've only been at it 8 days and have tried figuring most of it out myself along with reading here and google.
I created a bogus account if someone could stop in there. the USER is "test" the PASS is "test1" this way no one has to go through the hassle of registering. Maybe why your there you could critic my work. Try and remember it's a flowershop site and I still have about 700 more flowewr pics to upload.

So it's not complete yet. Thanks in advance.
